[0002] In modern construction, elevators, as a crucial vertical transportation device, are widely used on construction sites. Their primary function is to transport building materials, equipment, and workers from the ground to elevated work surfaces, significantly improving construction efficiency and safety. Traditional elevators typically utilize steel frames, equipped with electric motors and wire rope systems, capable of carrying heavy loads. However, as building heights continue to increase, the performance requirements for elevators are also becoming increasingly demanding. In recent years, the development of intelligent and automated technologies has brought new opportunities for elevator design and application. Modern elevators not only boast higher load capacities and faster operating speeds, but also incorporate intelligent control systems, enabling remote monitoring and fault self-diagnosis.
